Something has been off with Gamers Nexus for a while now.
He seems quite biased and unprofessional in the review.
Some of what he said does not even make sense, even more so because it was stuff he did not test but just made claims about.
For example he pointed out that the card ran quite hot and was no good for some cases despite the fact that it had lower temps than the reference card, this claim was made without actually testing in a suitable case. Also is he implying that the reference card is no good for those cases as well.
Quite a poor review and I did not like the way he was throwing the parts around regardless of whether he paid for the card or not.
The bios problems he talked about will get fixed and I am sure there will be an update soon.
For me if I wanted an 5700XT I would be very tempted to go for the XFX card as looks are important to some people in a 24/7 PC.
